Product details
Overview
TMS320F280040PMQR from Texas Instruments is a 100MHz C28x real-time MCU with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM (ECC/parity-protected), and 64-pin LQFP package. It integrates three 3.45MSPS 12-bit ADCs, seven PGAs, dual CAN, FSI, and ePWM with 150ps resolution-designed for high-precision motor control in EV charging power modules.
For engineers reviewing the TMS320F280040PMQR datasheet, TMS320F280040PMQR pinout, TMS320F280040PMQR application, or TMS320F280040PMQR equivalent, key selection criteria include functional safety support (FS-QM), CLA offloading capability, analog front-end channel count (14 ADC channels, 5 PGA inputs), and automotive-qualified Q-temp grade (–40°C to 125°C).
Technical Context
The TMS320F280040PMQR implements a dual-core real-time architecture: the 100MHz C28x CPU handles main control loops while the independent 100MHz CLA executes floating-point math tasks-including Park transforms in 13 cycles and trigonometric functions at 3×–4× speedup over software libraries. Its analog subsystem features three synchronized 12-bit ADCs with four post-processing blocks each and seven windowed comparators with integrated 12-bit DAC references.
Control peripherals include 16 ePWM channels with high-resolution (150ps) dead-band generation, two eQEP modules, seven eCAP modules (two with HRCAP), and four SDFM input channels. Communication is supported via two CAN ports, one PMBus, one I²C, two SPI, two SCI, one LIN, and one FSI interface-all pin-bootable and muxed across 26 GPIOs in the 64-pin PM package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280041PMQR | 128KB flash, same 64-pin PM package, but includes CLB and InstaSPIN-FOC™ ROM - no CLA in non-C variants. | Supports position manager logic and sensorless FOC out-of-box; better suited for motion control with encoderless BLDC. | Select when CLB-based custom logic or pre-validated FOC is required; TMS320F280040PMQR remains optimal for cost-sensitive, CLA-dependent designs. |
| TMS320F280040C-Q1 | Automotive-grade (AEC Q100 Grade 0), 100-pin PZ package, 256KB flash, CLB enabled - differs in package, temp range, and security features. | Qualified for under-hood automotive use; includes dual-zone security and UID for OEM firmware authentication. | Choose for automotive traction inverters or ADAS power supplies where AEC Q100 Grade 0 (–40°C to 150°C) and secure boot are mandatory. |
Compared with TMS320F280041PMQR and TMS320F280040C-Q1, the TMS320F280040PMQR offers balanced performance for industrial OBC and DC/DC converters-retaining full CLA capability and Q-temp qualification while omitting CLB and InstaSPIN to reduce cost and simplify qualification scope.
